I have been using a long-winded process to reduce some extraneous noise when digitizing mono vinyl sources. With Sound Forge, I have been subtracting the difference between the two channels of my records, on the assumption that most of it is noise, and the resultant files are usually audibly better.

1. Invert the phase of one of the two channels on the original .wav file (1.wav).2. Convert to mono by mixing the channels.3. Save the difference (noise file) as a mono .wav file (2.wav).4. Re-open the original "stereo" file (1.wav).5. Convert to mono by mixing the two channels.6. Save the sum as a mono .wav file (3.wav).7. Open original "stereo" file (1.wav).8. Open difference (noise) file (2.wav), copy it and overwrite onto left channel of 1.wav.9. *edit* Invert noise channel.10. Open sum file (3.wav), copy it and overwrite onto right channel of 1.wav.11. Convert to mono by mixing the two channels.12. Save changes to 1.wav.

Is there an audio editor that will allow me to subtract the difference of a stereo file in a single step, as it would save me a lot of time, and allow me to hear instantly whether the audio is significantly improved, without having to get confused by extra files? If I could work in flac, that would be even better.

If found the link below that references and old version of Cool Edit, but I gather that's been discontinued.

I have a segment of that recording, declicked, that doesn't seem too bad. However, it is in 32 bit floating point, my normal working format, and the size is 11meg+, an all day upload via this dial-up connection. It would be easier if resampled to 16 bit, but still pretty large. An mp3 version would obviously be easier yet. I need to know what you think you need to work with.

I also need to know where to send it. In another recent thread where this topic came up, cliveb said he just put whatever was involved as an attachment to his post. I find no option to allow that. Several other people also complained they see no way to do more than post a link (good only if one has someplace to which to link). Those in the know remained dumb to their pleas.

As you're composing your reply, there's a box labeled "File Attachments". Hit the Browse button to navigate to the file you want to attach. Then click the "Add this attachment" button. You should find after this that the file is listed in a panel within the "File Attachments" box. To actually put it in your posting, you need to click the "Add into Post" button. (Note: I don't think these options are available if you use "Fast Reply").
